Definitions
- the invention relates to a protective helmet with a connecting device for the releasable attachment of a strapless respirator, as described in the preamble of claim 1
- a protective helmet for the detachable attachment of a respiratory mask with a connecting device is known - according to DE-C3-2640701 -, in which both latching elements of the connecting device, which can be releasably engaged with one another, are arranged within the outer boundary of the protective helmet are.
- This connecting device consists, for example, of a latching bell, which is held via a holding element in a recess of the protective helmet, into which a latching element fastened to the respirator mask can snap, with an appropriate prestress between the respirator mask and the face of the user and the support of the counterforce via the protective home is disadvantageous here that the determination or adjustment of the contact pressure as well as the loosening of the fastening device is carried out by the bearing device of the connecting device penetrating the protective helmet and accordingly the protective helmet with relatively large openings and recesses must be provided.
- Another known protective helmet - according to EP-B1-0 105 813 - has a rigid calotte and an inner hood made of flexible transverse bands, the side parts of which converge at points symmetrical to the central longitudinal plane of the helmet and approximately at the level of the user's ears, the protective helmet being articulated on the removable respiratory protection mask by at least one adjustable length fastening arm.
- the cap of the protective helmet is provided with hooking notches or slots on the outside of each of its sides at the level of the user's ears for attaching two lateral fastening arms. These are connected to the respirator mask on both sides.
- Each of the lateral fastening arms has two telescopic elements which are connected to one another by resilient elements and are prestressed in such a way that they attempt to penetrate one another.
- a hook cooperating with the associated hooking notch of the calotte is pivotally mounted on the rear telescopic element of the fastening arm.
- stop means are provided, by means of which the two elements can be temporarily locked in the extended position.
- unlocking means are provided for these attachment means, by means of which the support of the fastening arms on the outer surface of the protective helmet can be triggered when the respirator mask is put on.
- connection devices between protective helmets and respiratory masks known from the prior art - according to DE-Cl-3300646 - which are constructed in such a way that the pretension or the pressing force of the respiratory mask on the face of the respirator is actuated by actuators on the respiratory mask It can be determined by the user that the connection devices, in particular with gloves, prove to be difficult to operate.
- a protective helmet with a respirator mask detachably attached to it is also known - according to DE-C3-2549 979 -, in which the connecting device is arranged in a recess in the calotte of the protective helmet and in the interior surrounding the protective parts projecting locking parts has, which directly engage in corresponding locking organs of the respirator.
- the locking parts or pins arranged in the connecting device and adjustable perpendicular to the protective helmet wall in the latching elements on the respiratory mask can be snapped in from outside the protective helmet, as can the release of the latching device. Due to the lack of a tensile connection between the two locking parts of the connecting device in the protective helmet and the latching elements on the respiratory mask, the two latching elements can disengage when the protective helmet is rotated or slipped relative to the respiratory mask.
- the present invention is based on the object of designing the connection device between the protective helmet and a strapless respirator in such a way that it is perfectly possible to put the respirator on even under difficult conditions
- a respirator mask or the snap clasp on the snap band enables this to have a high stability against kinking and thus it is also possible with one hand to push on the full face and a firm fit of the respirator mask with its contact surfaces on the face. Furthermore, despite the pivoting into the rest position within the protective helmet shell and any spatial deformation, trouble-free storage of the coupling parts is achieved
- the offset according to claim 5 is also advantageous, since obstacles are avoided when pivoting the coupling part in the spatially curved shell. Due to the advantageous further embodiment according to claim 6, the wearing comfort of the protective helmet is not hindered by the coupling parts and it can still be stored within the protective helmet without obstructing the other device parts, thereby also avoiding jamming when using the protective helmet without a respirator.
- the embodiment according to claim 7 allows the coupling parts to be stored as close as possible to the face and, on the other hand, prevents relative movements between the respiratory mask and the protective helmet in that both the supporting frame of the protective helmet and the coupling parts of the respiratory mask are mounted on the same supporting part, and the protective helmet can thus move relative to the support frame, for example to dampen impacts, without at the same time causing a change in the relative position between the support frame and the respiratory mask, which could lead to a leakage thereof.
- an embodiment according to claim 8 is also advantageous, since on the one hand this makes sufficient buckling rigidity possible for pushing the coupling part of the respiratory mask onto the coupling part on the protective helmet, regardless of the memory effect of the plastic used, and on the other hand a constantly constant opening - Take position for the coupling parts in their swung-out position to slide on the coupling parts of the respirator can be maintained even after a long period of use.
- a high-resistance training is achieved by the design according to claim 11 and it can also increase the pull-out strength for the anchorage between the respirator and the protective helmet.

- FIG. 1 shows a firefighter 1 who wears a protective helmet 2 and a respiratory mask 3 of a respirator 4 as personal protective equipment, which also includes bottles 5 in which the breathing air is stored under high pressure.
- the personal protective equipment of the firefighter 1 serves to make him independent of the ambient air, so that, as shown in the present exemplary embodiment, the fight against a fire with a jet pipe 6 is also possible in an atmosphere enriched with poisonous gases and possibly also low in oxygen.
- the strapless breathing mask 3 is connected via a connecting device 7 to a flank area 8 in the area of the ears of the fireman 1 and consists of two coupling parts 9 and 10 or connecting elements, one of which is attached to the protective helmet 2 and the other to the breathing mask 3 is.
- the respiratory mask 3 further comprises a viewing window 11, a mounting frame 12 for this viewing window 11 and a sealing edge 13 with which a sealing seal between the respiratory mask 3 and a face 14 of the fireman 1 is produced.
- the dosing of the breathing air from the bottles 5 takes place via a lung regulator 15.
- the supply of compressed air from the bottles 5 to the lung regulator 15 can be controlled via a control valve 16.
- the fireman 1 it is possible for the fireman 1 to carry only one bottle with breathing air or also several bottles with breathing air. Furthermore, it is also possible to use regeneration or circulation devices instead of the container devices. It is also irrelevant for the present invention whether normal pressure compressed air breathing apparatus with a regulator or overpressure systems are used.
- the protective helmet 2 comprises a protective helmet shell 17 in which a support frame 18 which is adjustably mounted in an inner helmet formed by a support frame and elastic bands for adaptation to the different head dimensions of the users.
- a head width of the support frame 18 can be adjusted by means of an tion 19 can be set.
- a support plate 20 is fastened to the support frame 18 in the flank area 8 of the protective helmet 2, for example via rivets 21, which has a pivot axis 22 of a joint arrangement 23 for holding a coupling part 24, which in the present case is formed by a locking band 25 and an axis of rotation 26 which a chin strap 27 is rotatable
- a visor 28 can also be swung out from a rest position shown in full lines within an interior 29, which is enclosed by the protective helmet shell 17, into a working position shown in dashed lines.
- This visor 28 is primarily intended for use without the breathing mask 3 shown at a distance from the protective helmet 2. However, it is also possible, with a corresponding design of the visor 28 and the respiratory mask 3, to use these simultaneously with one another.
- the breathing mask 3 comprises the viewing window 11, which is held in the mounting frame 12.
- the sealing frame 13 is connected to the mounting frame 12 and serves to seal the breathing mask 3 between it and the face 14 of a user.
- a holding bracket 30 is located on this sealing edge 13 arranged, which engages at two fastening points 31, 32 of the respiratory mask 3 on the sealing edge 13.
- a further coupling part 34 in the present case, for example, a locking clasp 35, is arranged over a cantilever arm 33 projecting over the holding bracket 30 in the direction of the viewing window 11.
- This locking clasp 35 consists of a U-shaped housing part 36, which consists of a base 37 and two Legs 38 and 39 arranged perpendicular to it are formed in the region of a front end 40, the two legs 38, 39 are connected to one another in the region of their upper edge by a transverse web 41.
- a pushbutton 42 is inserted between the two legs 38 and 39 and is pretensioned with a torsion spring in the direction of the base 37 of the housing part 36
- the coupling part 34 is also articulated about a pivot axis 22 of a joint arrangement 23 with the holding bracket 30 or the cantilever arm 33 and is thus rotatably or articulated on all sides.
- the opposite coupling part 24 assigned to this coupling part 34 consists in the present case of the locking band 25, which is tensile but flexible.
- this locking band 25 is provided with notches 43 arranged one behind the other at a short distance. These have an obliquely rising flank in the protective helmet shell 17 in the direction of the pivot axis 22, while that of the protective helmet shell 17 turned locking flanks are directed substantially perpendicular to a surface 44 of the locking band 25 from.
- the coupling part 24 has a reinforcing insert 45, which is shown schematically by dashed lines.
- the respirator mask 3 can be pressed against the face 14 with sufficient pressure in accordance with the respective shape of the face 14, so that after the pressure exerted on the respirator mask 3 in the direction of the face 14 to adapt the mask is supported by the support frame 18 of the protective helmet 2 firmly, and thus sealingly with its sealing edge 13, against the face 14 of the fireman 1 because the snap-in of the latch 43 of the latch 43 rests behind a latching flank, the respiratory mask 3 does not move in the opposite direction to the protective helmet 2 can move this away. If the fireman 1 has the feeling that the breathing mask 3 is too loose, he only needs to press the breathing mask 3 even more strongly against the protective helmet 2 in order to achieve a sufficiently firm fit.
- the position of the respiratory mask 3 can be changed and thus adapted to the length of the face 14 of the firefighter 1 without causing unwanted tension between the chin of the user and the protective helmet 2 is coming.
- the coupling part 24 or the locking band 25 in the rest position shown in full lines within the interior 29, which is enclosed by the protective helmet shell 17, is shown only schematically simplified.
- the coupling part 24 is rotatably mounted on the support plate 20 by means of the joint arrangement 23.
- the support plate 20 is in turn, as already described above, connected to the support frame 18 by means of the rivets 21. It is possible that the coupling part 24 can be pivoted out of its rest position drawn in full lines by means of the rotatable joint arrangement 23 into the working position, which is shown in broken lines.
- the coupling parts 24 are deformed by the shape of the protective helmet shell 17 or the shape of the support frame of the inner helmet or the visor 28, i.e. that the coupling parts 24 are slightly bent inwards in the end region, which would result in permanent deformation of the coupling parts 24 in the rest position if they remained for a long time.
- the reinforcing insert 45 which is preferably made of a steel strip, e.g.
- the permanent deformation of the coupling part 24 when pivoting out of the rest position can be canceled out by the fact that the reinforcing insert 45 consists of a material which is deformed back into its original shape after deformation and thus the coupling parts 24 in one, in relation to its longitudinal extension, spends a straight stretching position.
- the coupling parts 24 in their rest position either between the support frame of the inner helmet and the protective helmet shell 17 or between the support frame of the inner helmet and the support frame 18 of the inner helmet, whereby they are each pivoted through the shape of the support frame or the support frame 18 or the shape of the protective helmet shell 17 are spatially deformed.
- the copper plunging part 24 can be left in its rest position in the interior 29 over a longer period of time.
- the coupling part 24 is moved from its deformed position into the extended initial shape by the reinforcing insert 45, as a result of which a light connection can be made between the protective helmet 2 and the respiratory mask 3, since the coupling part 24 is light can be inserted into the coupling part 34 and runs easily in this.
- the coupling part 24 consists of the locking band 25, which is provided with catches 43 at one end and has a receiving device 46 at the end opposite it.
- the receiving device 46 has an opening 47 which is penetrated by the previously described pivot axis 22 of the joint arrangement 23 and thus a rotatable mounting of the coupling part 24 is ensured.
- a projection 48 in the opening 47 ⁇ order which leads to the limitation of the rotary movement and thus the pivot angle. This is e.g. ensures that the coupling part 24 can only be pivoted to a certain extent into the interior 29 of the protective helmet 2.
- the receiving device 46 is arranged offset with respect to the surface 44 in the direction perpendicular thereto.
- the latter has the catches 43 which are arranged on the surface 44 and which serve to lock the pushbutton 42 of the catch clasp 35.
- the individual catches 43 are arranged one behind the other, at the same distance from one another, transversely to a longitudinal central axis 49 of the catch strip 25 and have catch flanks 50 running perpendicular to the surface 44 and flanks 51 inclined obliquely in the direction of the receiving device 46. This ensures that when the locking band 25 is inserted into the locking clasp 35, the locking lug of the push button 42 slides up along the flanks 51 and is locked on the locking flank 50 in the opposite direction
- the reinforcing insert 45 is completely embedded in this in this exemplary embodiment. This can be done, for example, in an injection molding or extrusion process.
- the reinforcing insert 45 has a smaller width 52 than a width 53 of the locking band 25.
- a thickness 54 of the reinforcing insert 45 is also smaller in thickness 55 of the locking band 25, in the direction normal to its longitudinal extension. see.
- the locking band 25 thus has an approximately rectangular cross-section, the width 53 being a multiple of the thickness 55.
- An end face 56 of the reinforcing insert 45 is from an end region 57 of the locking band 25, which at the end of the locking band 25 opposite the receiving device 46 is arranged at a distance 58 therefrom and has a length 59 which extends in the direction of the receiving device 46. Both the distance 58, the thickness 54, and the length 59 can be varied depending on the design of the reinforcing insert 45 in order to ensure the necessary resilience in the extended position.
- openings 60 are provided which are spaced apart from one another in the direction of the longitudinal central axis 49. This ensures both a clear position in the injection mold and full-area and deformation-free embedding in the plastic of the locking band 25.
- the reinforcing insert 45 e.g. stainless steel, spring steel or material with a high elastic resilience or memory behavior can be used.
- a grid, net, threads, rods etc. instead of the reinforcing insert 45 shown in this exemplary embodiment, which is designed in the form of a flat profile, it being only important that these have a high resilience and do not permanently require themselves in their rest position.
- a stop 63 is optionally provided on a surface 62 of the locking band 25 opposite the surface 44, which stop e.g. serves to limit the insertion path of the locking band 25 into the coupling part 34 or represents a stop for the pivoting movement of the locking band 25. Above all, this also serves to prevent the two coupling parts 24 and 34 from jamming each other. These two surfaces 44 and 62 thus form the axial sides of the coupling part 24.
- the sandwich-like structure of the clutch 24 can be seen, the reinforcing insert 45 being surrounded on all sides by the plastic of the locking band 25 and on both sides of the flat sides of the reinforcing insert 45 designed in the manner of a flat profile, a layer of the material of the locking band 25 is arranged , as occurs especially during fire fighting, since the surrounding material of the locking band 25 keeps it away from the reinforcement insert 45 and thus isolates it, thereby protecting the user of such a combination of respiratory mask 3 and protective helmet 2 from additional injuries, in particular burns, is protected
- the coupling part 24, namely the locking band 25, is formed over its entire cross section, made of a plastic 64, which has a high memory behavior for the return movement of the coupling part into its straight stretched position.
- a plastic 64 which has a high memory behavior for the return movement of the coupling part into its straight stretched position.
- an alloy of different plastics, a component composed of layers of different plastics in the manner of a sandwich structure, or a combination of both can be used.
- the elastic material thus has properties such that the restoring movement or the restoring behavior of this material acts in a direction perpendicular to the flat sides forming the surfaces 44, 62. This ensures that, in turn, a simple and rapid coupling process between the coupling part 24 and the coupling part 34 arranged in the area of the respiratory protection mask 3 can be carried out perfectly.
- the coupling part 24, in the present case the locking band 25, is in turn provided with catches 43 at one end region 57 and has the receiving device 46 with the opening 47 and the projection 48 optionally arranged therein at the end opposite this.
- This receiving device 46 is penetrated by the pivot axis 22 of the joint arrangement 23 and is used for the rotatable mounting of the coupling part 24 in order to be able to pivot it out of its rest position within the interior 29 of the protective helmet 2 into its working position, that is to say for connection to the respiratory mask 3 .
- the catches 43 which are aligned transversely to the longitudinal center axis 49, are arranged on the surface 44 of the catch band 25 and serve for locking with the pushbutton 42 of the catch clasp 35.
- the individual catches 43 are one behind the other, at the same distance to each other, arranged in the direction of the longitudinal center axis 49 and have latching flanks 50 running perpendicular to the surface 44 and the flanks 51 inclined obliquely in the direction of the receiving device 46.
- the sloping flanks 51 serve to when inserting the locking band 25 into the locking clasp 35 to let the locking lug of the push button 42 slide up and then to lock the locking lug on the locking flank 50 running vertically to the surface 44 in the opposite direction to the insertion movement.
- the coupling part 24 which is only made of plastic 64, a corresponding resilience, it is essential that the coupling part 24 or the locking band 25 has the corresponding width 53 or thickness 55 with respect to its longitudinal extension 65 in order to reset it to be able to ensure its straight stretch position after the deformation.
- the stop 63 for limiting the insertion path into the coupling part 34, namely the locking clasp 35, is preferably arranged
- FIG. 10 shows a further embodiment for the arrangement of the reinforcing insert 45 within the coupling part 24 in a simplified representation in a front view.
- the reinforcing insert 45 is formed by two flat profiles 66 spaced apart from one another in the transverse direction to the longitudinal central axis 49, each of which has a width 67 and a thickness 54.
- Longitudinal end faces 68 of the flat profiles 66 facing one another are spaced apart from one another by a width 69.
- this width 69 can be arranged symmetrically to the longitudinal central axis 49.
- the reinforcing insert 45 in the form of a rod 70, which in the present exemplary embodiment has a circular cross section.
- a rod 70 which in the present exemplary embodiment has a circular cross section.
